The Yankees rotation is looking rather thin these days. After losing Michael Pineda to a forearm injury, the team was left with a gaping hole in their rotation behind Masahiro Tanaka, Nathan Eovaldi, Ivan Nova and CC Sabathia. Even before Pineda’s injury, the team already had a hole at the back of their rotation in Sabathia, whose days as a productive pitcher appear to be well behind him. Overall, that’s an underwhelming rotation for team that’s likely headed to the playoffs.

Somewhat curiously, the Yankees didn’t acquire any rotation help at the trade deadline. Even more curiously, it doesn’t seem like they made much of an effort to do so. Instead, they seemed more interested in fortifying the back of their bullpen, which is already one of the best in baseball.

The imminent arrival of top prospect Luis Severino may have been the primary reason for the Yankees’ inaction. Minutes after the non-waiver trade deadline had passed, Brian Cashman revealed the 21-year-old’s next start would be in the big leagues. He debuts tonight against the Red Sox.

Severino has little left to prove in the minor leagues. The hard-throwing righty split time between Double-A and Triple-A this year, where he recorded FIPs of 2.34 and 2.53, respectively. Severino was similarly dominant last season, when he rattled off a 2.46 ERA and 2.46 FIP across three minor league levels: Low-A, High-A and Double-A. Read the rest of this entry »

With Rick Porcello headed to the disabled list following a triceps injury, the Red Sox were in need of a starting pitcher for tonight’s start against the Yankees. Rather than turning to a Triple-A scrub to take Porcello’s spot in the rotation, the Sox opted to call up top prospect Henry Owens. Owens will take the mound in Yankee stadium tonight for his big league debut.

Owens, 22, has pitched exclusively at Triple-A Pawtucket this year, where he’s put up a 3.16 ERA and 3.68 FIP over 122 innings of work. The 6-foot-6 lefty has struck out 21% of the batters he’s faced, and has walked 11%. Other than Owens’ height, none of the figures cited above sound particularly impressive. Owens’ strikeout rate is hardly better than the International League average of 18.6%, and his walk rate is significantly worse than average. If you didn’t know any better, you might look at Owens’ 2015 stat line and conclude that he’s a fringe prospect.

Owens’ 2015 numbers may not be much to look at, but he performed markedly better in his first three seasons as a pro. In 2012, the year after the Red Sox took him 36th overall, Owens struck out 29% of opponent batters faced in Low-A. The next year, he whiffed 30% between High-A and Double-A in 2013. However, while the strikeouts were certainly encouraging, his 11% walk rate inflated his FIP to 3.61 over that span. Read the rest of this entry »

There’s no questioning that the Colorado Rockies’ rotation has been awful this season. In fact, by way of FIP-, the 2015 Rockies have the third worst rotation since 1915. As of this writing, not a single Rockies pitcher with more than 10 starts has a FIP that’s even above-average this year — which leaves fans with little to look forward to. That’s about to change, though, as the Rockies have summoned 23-year-old top prospect Jon Gray from Triple-A Albuquerque to start tonight’s game against the Mariners.

The Rockies drafted Gray third overall in the 2013 amateur draft out of the University of Oklahoma, and he immediately began to perform in the minor leagues. He closed out his draft year by pitching to a 1.93 ERA and 1.88 FIP in nine starts between Rookie Ball and High-A. Gray appeared to be on the fast track to the majors after such an exciting debut, but his performance tailed off substantially in Double-A last year. After striking out 26% and 42% of batters faced in Rookie Ball and High-A, respectively, he whiffed just 22% at the Double-A level. Along with a 8% walk rate, this resulted in a middling 3.91 ERA. KATOH forecasted Gray for just 2.3 WAR through his age-28 season. Read the rest of this entry »

With a 52-54 record and a meager 10% chance of making the playoffs, there likely won’t be much reason to pay attention to the Rays over the next two months. Simply put, it’s unlikely they’ll be playing too many more meaningful games from here on out. However, the Rays just got a bit more interesting today. They called up former first round pick Richard Shaffer from Triple-A Durham, who’s been one of the best hitters in the minor leagues this season.

Shaffer’s hit the crap out of the ball this year. The 24-year-old slugger opened the year in Double-A, where he hit .262/.362/.470 in 175 trips to the plate. The Rays promoted Shaffer to Triple-A in May, and he made it immediately clear that he was one of the best hitters at that level too. His .261/.353/.592 performance yielded a 168 wRC+, which is the second highest mark of any hitter with at least 200 plate appearances in the International League this season, trailing only Jerry Sands.

Shaffer’s 2015 performance has been undeniably excellent, but he hasn’t always enjoyed that same level of success. In 2013 and 2014, he posted wRC+s of 99 and 112, respectively. Since Shaffer was a bat-first prospect, that performance pushed him to the fringes of the prospect radar. At first glance, it might appear as though Shaffer’s 2015 breakout came out of nowhere, and that it’s only a matter of time before the unfeeling hand of regression pushes him back towards mediocrity. But there’s reason to believe that Shaffer’s improvements are for real, and that he very well might be the hitter his 162 wRC+ in Triple-A suggests he is. Read the rest of this entry »

This was a crazy trade deadline. Dozens and dozens of players changed teams, including several stars who were dealt in the final days. I did the best I could to keep up with my KATOH posts for all of the trades, but still let a few smaller deals fell through the cracks.

In this post, I catch up on the guys I missed. There are no blue-chip prospects here, but a few of the players listed below have decent shots of being big-league regulars in the near future. I put together brief write ups on the more notable prospects from these deals, and then merely listed the guys who are unlikely to ever be impact major leaguers. (Note: WAR figures denote WAR through age-28 season.)

Zach Davies, Milwaukee Brewers, 5.8 WAR

Zach Davies has spent the 2015 season in Triple-A, where he’s pitched to an excellent 2.84 ERA and a similarly excellent 3.10 FIP. He doesn’t throw particularly hard, but he’s still managed to post average-ish strikeout and walk numbers in Triple-A, which is no small feat coming from a 22-year-old. Furthermore, he’s managed to induce plenty of ground balls (54% ground-ball rate according to MLBfarm), which helps explain how he’s allowed just four homers in over 100 innings on the year.

Just minutes before the non-waiver trade deadline, the Mets finally landed the offensive spark plug they were looking for. They swung a deal for outfielder Yoenis Cespedes from the Detroit Tigers in exchange for pitching prospects Michael Fulmer and Luis Cessa. Here’s what my fancy computer math has to say about these two minor league hurlers and their respective big league futures. Read the rest of this entry »

Days after acquiring Scott Kazmir, the Astros went out and bought more players last night. This time around, they acquired Carlos Gomez and Mike Fiers in exchange for four prospects: Brett Phillips, Domingo Santana, Adrian Houser and Josh Hader. Let’s take a look at how this quartet of minor leaguers projects. (Note: WAR figures denote WAR through age-28 season.)

Brett Phillips, 3.7 WAR

Brett Phillips, 21, has split the 2015 season between High-A and Double-A where he’s hit .320/.377/.548 in 97 games. Phillips hit for gobs of power (.268 ISO) at the former location, but it’s yet to show up (.142 ISO) at the latter. Still, his ability to get on base has enabled him to post a 133 wRC+ since his promotion. Phillips also has above-average speed, which shows up in his stolen-base numbers.

In yet another blockbuster deal, the Toronto Blue Jays have landed David Price from the Tigers in exchange for lefty hurlers Daniel Norris, Jairo Labourt and Matt Boyd. More pitching prospects on the move! Once again, I’ve applied my fancy computer math to these players to try to get some sense of these pitchers’ futures. If you’re looking for scouting reports on these players, check out Kiley’s write up of this trio. (Note: WAR figures denote WAR through age-28 season.)

Daniel Norris, 4.8 WAR

The centerpiece of the players headed to Detroit is easily Daniel Norris, who was widely considered to be one of the top-20 prospects in baseball heading into the year. Norris enjoyed a meteoric rise through the Blue Jays farm system in 2014. After 13 dominant starts at High-A, the Blue Jays bumped him up to Double-A for eight starts, and then Triple-A for four starts, before giving him a taste of the big leagues last September. Norris pitched to a 2.53 ERA and 2.57 FIP in the minors in 2014.

The Dodgers, Marlins and Braves have pulled off a massive trade that sends Mat Latos and Alex Wood to the Dodgers, and a whole slew of other players (plus a draft pick) in other directions. The prospects involved include Jose Peraza, Kevin Guzman, Jeff Brigham, Victor Araujo and Zachary Bird. Here’s what the data say about these players. (Note: WAR figures denote WAR through age-28 season.)

Jose Peraza, Los Angeles Dodgers, 8.7 WAR

Jose Peraza is easily the most highly touted prospect who changed hands in this deal. The 21-year-old second baseman was playing in Triple-A this year, where he was hitting an admirable .294/.318/.379 with 26 steals. He put up much better numbers in the lower levels of the minors, however, including a .339/.364/.441 showing between High-A and Double-A last year.

Peraza’s offensive game is centered entirely around contact and speed. He’s struck out in just 8% of his trips to the plate this year, and has struck out less than 13% of the time in each of his five years in the minors. Peraza’s lack of strikeouts, along with his solid BABIPs, have enabled him to hit for high averages throughout his minor-league career.

What a time to be alive. In a span of hours, Carlos Gomez was almost traded to the Mets; Wilmer Flores cried on the field; and the Dodgers, Braves and Marlins all but completed a deal that seemingly involves dozens of players. But most exciting of all, Cole Hamels is heading to the Rangers in an eight-player deal that also includes Jake Diekman, Matt Harrison, Nick Williams, Jorge Alfaro, Jake Thompson, Jerad Eickhoff and Alec Asher. Here’s what my fancy computer math has to say about the five prospects headed to Philly in the trade. Read the rest of this entry »
