A year ago, Jesús Aguilar took the starting first base job in Milwaukee away from Eric Thames, hitting 35 homers and posting a 135 wRC+ as the Brewers rolled to a division title. This year, Aguilar’s struggles opened the job back up for Thames; Aguilar has been relegated to the weak side of a platoon. A strong month of July in part-time duty wasn’t enough to play him back into a starting role with the Brewers, but it was enough to get the Tampa Bay Rays interested and willing to part with a pitcher the Brewers can use for their own pennant drive. As first reported by Jeff Passan:

Brewers Receive

• RHP Jake Faria

Rays Receive

• 1B Jesús Aguilar

For the Rays, the need for a right-handed bat is obvious. The left-handed Austin Meadows and Nathaniel Lowe have been getting starts at first base and designated hitter against lefties, with Ji-Man Choi only playing against righties and catcher Travis D’Arnaud getting time at first as well. Aguilar and his righty bat should be able to relieve some of the poor matchups the Rays have found themselves in. Aguilar has bad splits against lefties this season, but that’s more likely a product of generally hitting poorly and some randomness than weird reverse platoon splits. And while his 2019 performance has been wanting, with an 82 wRC+, he’s shown some signs of putting things together over the last month, as the rolling wRC+ graph shows.

Monday’s trade of Jason Vargas to the Phillies wasn’t exactly a blockbuster, but it was noteworthy as the rare intradivisional pre-deadline swap. Some might view in-season deals with direct rivals to be taboo, but they do occur, and as today’s one-size-fits-all deadline approaches, I thought it might be fun to take a quick look at the recent history of such trades.

To keep this from becoming unruly, I’m confining my focus to the 2012-19 period, the era of two Wild Cards in each league — a cutoff chosen because it expands not only the number of teams who make the playoffs, but also the group who can at least envision themselves as contenders. For this, I’m using the Baseball-Reference Trade Partners tool and counting only trades that occurred in June, July, or August, which we might more accurately call midsummer deals rather than deadline ones — though some of them were definitely of that variety. I’m omitting straight purchases, which generally involve waiver bait, though I have counted deals in which cash changed hands instead of a player to be named later.

In a trade that may or may not dissolve Coldplay, the Braves cushioned their bullpen on Tuesday night by acquiring right-handed reliever Chris Martin. Per The Athletic’s Ken Rosenthal, the Braves obtained Martin from the Rangers in exchange for Triple-A lefty Kolby Allard.

The Braves currently have a fairly large lead over the Nationals atop the NL East, and we have them as the favorite (68.5%) to win the division. To this point, the bullpen has been one of Atlanta’s few weaknesses. Braves relievers have posted a 4.75 FIP and accrued -0.1 WAR this season, the sixth worst total in baseball. Walks have been particularly problematic for this crew, as they’ve allowed an 11% walk rate, the second worst mark in the league. A high strand rate has masked the issue somewhat — the ‘pen has notched a 4.03 ERA — but Atlanta needs reinforcements.

Martin should help. After dominating in the NPB — he posted a 91-to-13 K/BB in 88.1 IP back in 2017 — he’s pitched well since returning stateside the following year. In 2019, he’s been fantastic, and he sports a 3.08 ERA (62 ERA-) in 38 innings. His 26.5% K-BB rate is the 15th-highest among the 182 relievers with at least 30 IP, and he recently went nearly two months without walking a batter. He’s also pitched in plenty of stressful situations: Among Braves relievers, only Luke Jackson has a higher average leverage index this year than Martin. Read the rest of this entry »

The Cold A/C League needed a bit of recharging, with Marcus Stroman’s move to the Mets the only major trade so far this deadline. With only 18 hours to go, the Indians provided a big one, sending pitcher Trevor Bauer to the Cincinnati Reds in a three-way trade that included the San Diego Padres. I like to approach three-way trades as three individual trades to keep things from getting confusing, like a Westerosi family tree.

Cincinnati Reds acquire P Trevor Bauer in return for OF Yasiel Puig, OF Taylor Trammell, and P Scott Moss

Cincinnati made aggressive, short-term moves to improve the team last winter, acquiring Puig, Sonny Gray, Tanner Roark, and Alex Wood in an attempt to jump-start their transition from rebuilder to contender, much the Braves and Phillies did in 2018. While not everything went according to plan — Wood has been injured and Puig got off to a slow start — it’s hard to say the moves were a failure. If the playoffs were determined by Pythagorean record, the Reds would be in the thick of the Wild Card mêlée, in third place and two games behind the Washington Nationals (as of the moment this trade hit the wires).

Alas, the playoffs are not determined by Pythagorean record.

Tampa Bay’s pre-deadline activity — trading bat-first prospect Nick Solak for electric reliever Peter Fairbanks, then moving recently-DFA’d reliever Ian Gibaut for a Player to be Named, and sending reliever Hunter Wood and injured post-prospect infielder Christian Arroyo to Cleveland for international bonus space and outfielder Ruben Cardenas, a recent late-round pick who was overachieving at Low-A — got us thinking about how teams’ anticipation of the fall 40-man deadline might impact their activity and the way they value individual prospects, especially for contending teams.

In November, teams will need to decide which minor league players to expose to other teams through the Rule 5 Draft, or protect from the Draft by adding them to their 40-man roster. Deciding who to expose means evaluating players, sure, but it also means considering factors like player redundancy (like Tampa seemed to when they moved Solak) and whether a prospect is too raw to be a realistic Rule 5 target, as well as other little variables such as the number of option years a player has left, whether he’s making the league minimum or in arbitration, and if there are other, freely available alternatives to a team’s current talent (which happens a lot to slugging first base types).

Teams with an especially high number of rostered players under contract for 2020 and with many prospects who would need to be added to the 40-man in the offseason have what is often called a “40-man crunch,” “spillover,” or “churn,” meaning that that team has incentive to clear the overflow of players away via trade for something they can keep — pool space, comp picks, or typically younger players whose 40-man clocks are further from midnight — rather than do nothing, and later lose players on waivers or in the Rule 5 draft.

As we sat twiddling our thumbs, waiting for it to rain trades or not, we compiled quick breakdowns of contending teams’ 40-man situations, using the Roster Resource pages to see who has the biggest crunch coming and might behave differently in the trade market because of it. The Rays, in adding Fairbanks and rental second baseman Eric Sogard while trading Solak, Arroyo, etc., filled a short-term need at second with a really good player and upgraded a relief spot while thinning out their 40-man in preparation for injured pitchers Anthony Banda and Tyler Glasnow to come off the 60-day IL and rejoin the roster. These sorts of considerations probably impacted how the Cubs valued Thomas Hatch in today’s acquisition of David Phelps from Toronto, as Hatch will need to be Rule 5 protected this fall.

For this exercise, we used contenders with 40% or higher playoff odds, which gives us the Astros, Yankees, Twins, Indians, Red Sox, and Rays in the AL and the Dodgers, Braves, Nationals, Cubs, and Cardinals in the NL, with the Brewers, Phillies, and A’s as the teams just missing the cut.

The Cubs and Blue Jays agreed to a trade this afternoon, sending David Phelps to the North Siders in exchange for pitching prospect Thomas Hatch. The Cubs are locked in a tight divisional race with the Cardinals and the Brewers, tied for first place entering today’s play. They are the favorites to win the division (we have their division odds at 56.8%), but they have been hampered by a weak bullpen all year. The Phelps trade is an attempt to shore their biggest weakness up.

The Cubs relief corps is a motley assortment of over-30 stalwarts (Steve Cishek, Brandon Kintzler, Brad Brach, and Pedro Strop), converted starters (Tyler Chatwood and new addition Derek Holland), and Craig Kimbrels (Craig Kimbrel). Out of the entire bullpen, only Kyle Ryan, Rowan Wick, and Kintzler have provided even 10 innings of sub-4 FIP performance, which explains the group’s collective 4.22 ERA, 4.66 FIP, and 0.1 WAR. While some of that dicey performance was traded (Mike Montgomery) or optioned to Triple-A (Carl Edwards Jr.), it’s still a position of need.

Can Phelps fulfill that need? It’s an interesting question, and Phelps is about as interesting as you can get for a journeyman reliever with 0 WAR on the year. As recently as 2016, Phelps was a dominant reliever (in his first year after converting from starting), throwing 86.2 innings and amassing a 2.28 ERA and 2.8 FIP. In the middle of a strong 2017, he was traded, as all players must eventually be, to the Mariners, where he promptly had elbow problems. A bone spur in his throwing arm cut that season short, and if that sounds ominous to you, it should: he subsequently tore his UCL in spring training, and missed all of 2018 and the start of 2019 recovering.

Before his injury, Phelps was a prototypical bullpen arm. He sat 94-95 with a sinker/four-seam combination and occasionally touched 98. The velocity hasn’t come back, at least not completely; he’s closer to 92-93 in his 17 appearances with the Blue Jays this year. To compensate for that lost velocity, he’s featured a cutter much more since returning (32.3% of his pitches this year). He also boasts a swooping curveball that he uses mainly as a change of pace.

The Phillies have bolstered the back-end of a flagging rotation, which by some measures ranks among the National League’s worst. What’s more, they’ve done so through an upgrade obtained from within the division, namely the Mets’ Jason Vargas. The 36-year-old southpaw doesn’t light up radar guns or dominate hitters, but he does give a youngish rotation a left-handed presence with playoff experience — and at a negligible cost to boot. His being dealt by the Mets was highly anticipated, not only given Sunday’s acquisition of Marcus Stroman, but also because he angered the Mets’ brass with his involvement in a clubhouse altercation with a beat reporter in June.

Philadelphia gets:

LHP Jason Vargas
Cash considerations

New York gets:

C Austin Bossart

Vargas, who is now in his 14th major league season, has rebounded from a dreadful, injury-wracked 2018, during which he was torched for a 5.77 ERA and 5.02 FIP in just 92 innings, and an ugly beginning to this year when he yielded 10 runs in his first 6.1 innings and failed to last five innings in three of his first four starts. Overall, he’s pitched to a 4.01 ERA and 4.71 FIP, and since returning from a mid-May left hamstring strain that cost him 19 days, he’s turned in a 3.34 ERA and 4.01 FIP.

The Brewers and Pirates agreed to a minor trade on the Trade Deadline’s Eve-Eve, with Jordan Lyles heading to the Milwaukee Brewers for Double-A starter-turned-reliever Cody Ponce.

There’s little question that the Brewers are sorely in need of an additional starting pitcher for the stretch run. The rotation wasn’t exactly a source of strength for the team even before losing Jhoulys Chacin and Brandon Woodruff to abdominal injuries over the last week. With those two not expected to return quickly — Chacin isn’t expected until mid-August and it may take Woodruff into September — and the trade deadline approaching, the Brewers don’t have much margin for error. It would have been a phenomenal risk for the team to hope that the respective rehab stints of Brent Suter and Jimmy Nelson go extremely well, allowing them to arrive dramatically like Marshal Blücher at Waterloo.

Now, is Jordan Lyles the pitcher you want to bring in as your emergency replacement? That I’m less sure of. But I’m not as instantly dismissive as I normally would be of a pitcher sporting a 5.36 ERA. Lyles was actually quite effective for most of the season, his ERA not rising over four until his first start in July. His pummeling has been largely limited to three atrocious starts in which he allowed a total of 19 runs over 6 1/3 innings. He’s been bitten by both home runs (eight homers in four starts) and by BABIP (.556) and while he’s no doubt pitched poorly, he’s been that combination of lousy and unlucky. I’m not sure batters would have a .556 BABIP off a five-year-old pitching with the wrong hand.

For the season, Lyles has a 4.38 xFIP and ZiPS, which doesn’t just assume high home run totals are a fluke but looks at the detailed hit data, thinks he has allowed five more home runs than he ought to have based on those stats. StatCast’s data agrees with this, giving Lyles an xSLG against of .438, well below his actual .514. Read the rest of this entry »

On Saturday, the Marlins and Twins pulled off a pre-deadline swap.

First, the trade:

Miami gets:

1B Lewin Diaz

Minnesota gets:

RHP Sergio Romo
RHP Chris Vallimont
Player to be Named Later

This deal’s immediate big league relevance centers around 36-year-old Romo, who has had an incredible career for a reliever, especially one who throws as hard as he does. Romo’s fastball has never averaged more than even 90 mph, topping out at 89.9 mph during his rookie year, while average relief fastballs now hum in at 93.6 mph. His 9.8 WAR ranks 15th among relievers since he debuted in 2008, and splitter wizard Koji Uehara is the only other soft-tosser ahead of him.

Most of our readers have probably seen enough of Romo over the last decade to know that he’s been exceptional because of his ability to locate, and change the speed and shape of, his trademark slider. Hitters know that slider is coming — he’s thrown it roughly 53% of the time during his career, second most to Carlos Marmol among all pitchers with 400 or more innings since Romo debuted — and yet Romo’s surgical placement of the pitch just off the plate, equal parts enticing and unhittable, has had big league hitters flailing away at it across more than a decade now.

Teams have been smiling at each another and making their fair share of prolonged eye contact, but the trade deadline tension had yielded little in the way of actual consummation until Saturday’s A’s and Royals trade that sent veteran lefty reliever Jake Diekman to Oakland for two prospects. Here’s the deal:

Oakland gets:

LHP Jake Diekman

Kansas City gets:

RHP Ismael Aquino
CF Dairon Blanco

Diekman, who has struck out 33.5% of opposing hitters and has a 3.37 FIP across 41.2 innings this year, immediately becomes the best lefty in Oakland’s bullpen, surpassing cutter/curveball/command lefty Ryan Buchter (who was also acquired from Kansas City via trade last year), and strike-throwing Taiwanese depth piece, Wei-Chung Wang. That’s less a knock on either of those two, and more to do with Diekman, who has been good with uncommon consistency for a reliever throughout his seven-year big league career.
