C.J. Wilson's transition from bullpen to rotation has been huge for the Rangers

5 Comments

After four years spent exclusively as a reliever C.J. Wilson convinced the Rangers to give him the chance to claim a rotation spot this spring and five months later he’s been one of the best starting pitchers in the American League.
Wilson shut out the Royals for 7.2 innings yesterday, improving to 14-5 with a 2.88 ERA and 140 strikeouts in 171.2 innings. He leads the league with 77 walks, but has made up for it by having the league’s lowest opponents’ batting average and remarkably giving up just eight homers in 707 plate appearances despite calling Texas’ hitter-friendly ballpark home.
He’s been absolutely unhittable against left-handed batters, holding them to a .124 average and zero homers in 129 at-bats, and even right-handers are hitting just .227/.327/.333 against him. He’s essentially taken his effectiveness as a reliever and transferred it almost exactly to starting, all while throwing 100 more (and counting) innings than ever before.
What’s interesting about Wilson’s transition from relieving to starting is that he’s thrown significantly fewer fastballs than he did working out of the bullpen. Each season from 2005-2009 he threw at least 70 percent fastballs, but this year he’s relied on the pitch just 49.1 percent of the time, which is the sixth-lowest rate among all AL starters.
Wilson is throwing a cutter far more, with a great deal of success, and has also leaned heavily on his curveball and changeup after years of barely using either pitch. As a reliever Wilson threw his fastball or slider 90-95 percent of the time, but as a starter he’s used those two pitches just 62 percent of the time. Wilson believed he had the stuff to succeed as a starter, the Rangers gave him the opportunity at age 29, and now he’s got the fourth-best ERA in the league for a first-place team.
Plus, he’s great to follow on Twitter.

In a wave of prospect advancement news on Sunday, the Rockies have joined the fray. The Astros are calling up Alex Bregman. The Diamondbacks are calling up Braden Shipley. And the Rockies will call up outfield prospect David Dahl on Monday, Nick Groke of The Denver Post reports. The Rockies are expected to designate outfielder Brandon Barnes for assignment to create roster space.

Dahl, 22, was selected by the Rockies in the first round — 10th overall — in the 2012 draft. He started the season at Double-A, batting .278/.367/.500 with 13 home runs, 45 RBI, 53 runs scored, and 16 stolen bases in 322 plate appearances. He earned a promotion to Triple-A Albuquerque earlier this month. In 16 games there, Dahl has hit an outstanding .484/.529/.887 with five homers, 16 RBI, and 17 runs scored in 68 plate appearances.

Dahl is considered the Rockies’ second-best prospect and #40 overall in baseball according to MLB Pipeline. He got some camera time during the 2016 Futures Game two weeks ago, going 0-for-2.

David Robertson got the win in both White Sox victories today, a double-header versus the Tigers. In the first game, he got the final out of the eighth inning and pitched a scoreless ninth before the White Sox walked off on an Adam Eaton RBI single.

It was the second game that made things interesting. Robertson took the mound at the start of the ninth inning staked to a 4-1 lead. He’d fork up a leadoff home run to Nick Castellanos. Then, after getting two outs, served up another solo shot to Tyler Collins followed by a game-tying Jarrod Saltalamacchia dinger. Robertson would get out of the inning without any further damage.

In the bottom of the ninth, Melky Cabrera sent the White Sox home winners again, drilling a walk-off RBI single. That gave Robertson the win, his second of the afternoon. As Baseball Tonight notes on Twitter, Robertson is the first player in the last 100 years to give up three home runs in an inning or fewer and still wind up with the victory.

Robertson has had a rough go of it since the All-Star break. He yielded four runs in his first appearance back on July 18. On the season, he’s saved 23 games in 27 appearances with a 4.46 ERA and a 50/21 K/BB ratio in 40 2/3 innings.
