Thoughtless and bad editor Carson Cistulli overlooked this post when Chris Mitchell submitted it on Friday afternoon. That’s the reason it’s appearing on Tuesday.

The Mariners and Cardinals completed one-to-one swap of outfielder Tyler O’Neill and lefty Marco Gonzales on Friday. As Dave Cameron has pointed out, this represented a case of the Mariners trading away future upside for some much-needed, immediate rotation depth. A move of that type is understandable given the state of the Mariners’ rotation and their position in the Wild Card race, but KATOH thinks the gap in value between these two prospects is quite large.

Below are the projections for the three players whom the White Sox receive. WAR figures account for the player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

Tyler O’Neill, OF (Profile)

KATOH: 7.1 WAR (34th overall)
KATOH+: 6.0 WAR (52nd overall)

O’Neill elevated his prospect stock last season, when he slashed .293/.374/.508 at the Double-A level. But he’s had a tougher time at Triple-A this season, hitting only .244/.328/.479. Part of that, however, has to do with playing in a park that’s tough on right-handed hitters. Eric Longenhagen gave him a 50 FV over the winter and listed him as an honorable mention on his top-100 list.

O’Neil is a three-true-outcomes prospect who’s homered, walked, or struck out in over 43% of his trips to the plate this year. His power is his biggest strength, as he’s belted a remarkable 75 homers since the start of the 2015 season while also kicking in 76 doubles and triples. But all that power comes with a lot of strikeouts, as evidenced by his 27% strikeout rate this year.

On Friday afternoon at Wrigley Field, with the Cardinals trailing the Cubs 3-2 heading to the seventh inning, Mike Matheny called on left-handed reliever Zach Duke to replace his starting pitcher Carlos Martinez. Duke turned around Ben Zobrist to bat right-handed, inducing a fly out to left field, before snaring a weak liner back toward the mound off the bat of Anthony Rizzo. With the right-handed hitting Willson Contreras due next, Duke was relieved by right-handed throwing Matt Bowman, who promptly recorded the third out. All told, Duke threw just six pitches, three for strikes.

On its own, Duke’s appearance doesn’t appear noteworthy. Nothing spectacular happened, and Duke has pitched in a lot of games. In fact, over the past three full major-league seasons, Duke was about as likely as anyone in the league to make an appearance on the mound in a game.

So what made Duke’s appearance special? To understand that, it’s necessary to begin with the fact that this was his first appearance in an MLB game in 2017. As the regular season ended last season in early October, the Cardinals reported that Duke had undergone Tommy John surgery while also having a flexor muscle repaired in this left arm.

Tommy John surgery has become something with which all baseball fans are familiar. At this point, it’s no longer shocking to hear that a pitcher has torn a UCL in his throwing elbow. By my calculations, over 26% of pitchers who appeared in an MLB game last season have had this type of procedure.

Heading into the year, the Mariners plan seemed to be to acquire as many low-ceiling middling prospects as they could find and throw them all at the wall, hoping one or two would help stabilize the back end of the team’s rotation. Over the last year and change, they’ve acquired and started Ariel Miranda, Dillon Overton, Chase De Jong, Chris Heston, Christian Bergman, and Ryan Weber. Thanks to a .220 BABIP, Miranda’s been a reasonable enough starter for the team, but most of the other guys made a few low-quality appearances and were then shipped back to Triple-A.

But the Mariners are apparently undeterred, and are trying this strategy one more time.

It’s that time of year again. Time to gather around adult beverages (drink specials to be determined) and small plates (free thanks to FanGraphs, October, and The Athletic!) and talk baseball with some of your favorite writers. Thursday, July 13th, at 7pm at Local Option in Chicago, we have invited the writers, analysts, and brewers below (and a few more off list) to come and be merry with you in the back of the bar.

This is a 21-and-over event. No tickets required.

See you soon.

Baseball is flush with randomness. Time and time again, we trick ourselves into believing we have a good sense of what’s going to happen next, armed with an ever-growing arsenal of measurements, metrics, and projections. Yet, without fail, baseball constantly finds a way to catch us by surprise. One of those surprises has taken St. Louis by storm the last couple of weeks. First baseman Luke Voit debuted for the Cardinals on June 25th and has proceeded to hit .333/.379/.704 between then and now. He’s currently sporting a 179 wRC+, which as the title suggests, is one of the best in baseball among batters with at least 29 plate appearances.

Of course, 29 plate appearances is too few to tell us much of anything about what Voit will do going forward. Luckily, Voit has a lengthy minor-league track record that can. And now that you’ve fallen for the clickbaity title, you’re stuck reading about it.

While surprising, Voit’s performance didn’t come completely out of nowhere. He was a good hitter in the minors, amassing over 30 homers since the start of 2015. He slashed .322/.406/.561 at Triple-A this year and .297/.372/,477 in 2016 at Double-A. Voit also managed to keep his strikeout rate comfortably below 20%, which allowed him to hit for both average and power.

On Monday, while investigating Jonathan Lucroy’s mysterious framing decline, I noted that Buster Posey and Yadier Molina have also had noticeable falls from the framing elite this season.

Posey ranked as the game’s best framing catcher last season (26.5 framing runs), according to Baseball Prospectus , and has fallen to 28th thus far this season, with just 0.5 framing runs to his credit. Molina has fallen from ninth last season (9.0 framing runs) to 38th (with a mark of -0.5).

Let us consider, for a moment, the matter of Mike Leake.

The mental image you have of Leake is probably that of a serviceable mid-to-back-end starter. Leake doesn’t strike many guys out, and he’s perhaps walked a few too many men for comfort considering his lack of punchouts. Leake does not make your team a contender, but he makes it viable. He’s a good bowl of potato leek soup if you’ll pardon the unwitting pun: not your first choice on the menu, but one that’s hearty and comforting when done right. Teams need good bowls of soup. They’re not much if they only have superstars and super-scrubs. They need something in the middle. They need arms to throw decent innings. Mike Leake has been that man for years.

Until now, perhaps. Before Clayton Kershaw took the mound last night and threw nine innings of one-run ball, Leake had the lowest ERA in the National League at 2.03. Kershaw has now assumed his rightful place at the head of the pack with a 2.01. That would seem like a return to normalcy — that is, if Leake’s 2.03 ERA itself weren’t so abnormal.

As you might suspect, the underlying metrics don’t think Leake is pitching exactly this well. His 3.18 FIP is still quite good, while his 3.73 DRA is less enthusiastic. His ground-ball rate is identical to last year’s, while he’s allowing fewer line drives and more fly balls. Opposing batters are putting just .244 when they put the ball in play against him, which is interesting considering that the Cardinals haven’t been all that great on defense this year. He’s not creating especially soft or hard contact, either. He’s near the middle of the league in average exit velocity.

So what exactly is going on here? How does a soul-warming bowl of soup turn into a delicacy?

Let us consider, for a moment, the St. Louis rotation.

When you look up and see that the Athletics are in the midst of a two-game mid-week series against the Marlins in late May, you might suspect that the major-league baseball schedule is simply an exercise in randomness. At this point in the campaign, that’s actually sort of the case. The combination of interleague play and the random vagaries of an early-season schedule conspire to mean that your favorite team hasn’t had the same schedule as your least favorite team. Let’s try to put a number on that disparity.

With outfielders Dexter Fowler, Stephen Piscotty and Jose Martinez all out of commission, the Cardinals called up 21-year-old Magneuris Sierra to play center for the time being. Sierra was off to a fine start in High-A this year, hitting .272/.337/.407 through 20 games. But of course, all of that came against pitching that was not one, not two, but three levels below the big leagues.

Sierra’s hitting has never been his calling card, however, as his prosoectdom is centered around his speed and defense. Lead prospect analyst Eric Longenhagen described him as having “Gold Glove-caliber tools in center field” last month and gave both his speed and defense future grades of 70 over the winter. Those tools have translated to on-field performance in the lower levels, as he swiped 31 bags in Low-A last year and clocked in above average in center according to both Clay Davenport’s and Baseball Prospectus’ defensive numbers.

Over the winter, the Cardinals talked a lot about upgrading their defense and getting more athletic in the outfield ,in particular. They let longtime Cardinal Matt Holliday go become a DH in the American League, preferring not to put his glove in left field any longer. After trying to trade for Adam Eaton, they eventually signed Dexter Fowler to play center field, allowing them to move last year’s center fielder (Randal Grichuk) back to left field.

Fowler’s not a great defender, but Grichuk is a better athlete than most left fielders, and Piscotty appears to be a decent right fielder, so this group looked like a solid-enough group of gloves. It’s not the Rays or the Red Sox, but the new Cardinals outfield looked capable of running down enough balls in the gap that outfield defense wouldn’t be a huge problem.
