Rick Porcello had to battle just to keep his rotation spot this spring, but he’s currently showing some signs of a breakthrough.
Porcello allowed three hits and no walks over seven scoreless innings last night in a 3-0 victory over the Twins. While he still holds a mediocre 4.37 ERA for the year, he has a 2.84 ERA and 56/10 K/BB ratio in 57 innings over his last nine starts.
As Neil Weinberg of New English D points out, Porcello’s success goes well beyond ERA. The 24-year-old currently has career-bests in strikeout rate (7.59 K/9), walk rate (1.59 BB/9) and ground ball rate (56 percent). It makes for a pretty valuable combination.
He’s striking out more than 7 batters per 9, walking fewer than 2 batters per 9 and has a groundball rate above 50%. From 2000-2012, here is the list of pitchers who have finished a season with that mix: Halladay (4x), Carpenter (3x), and Hamels (1x). In 2013, the pitchers on that list are Felix Hernandez, Doug Fister, and Rick Porcello. That is some excellent company.
If we push the limits farther, to 7.5 K/9, 2.0 BB/9 and 55% GB (which Porcello has) the list of pitchers since 2000 to accomplish that feat drops to zero. Nobody. We don’t have groundball data from before the early 2000s, so I can’t tell you how rare this is in MLB history, but since the data became available, it’s never been done.
Very interesting. While it’s easy to write this off as a hot streak given Porcello’s past results, it’s important to note that he has altered his pitching mix, adding in more curveballs and changeups than ever before. If he has truly taken a step forward as a pitcher, the Tigers’ rotation could be more dangerous than we already thought.
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.
