Scout on Aroldis Chapman starting: “Joba Chamberlain all over again”

Ken Rosenthal talked to a rival scout about the chance of Cincinnati Reds lefty Aroldis Chapman joining the starting rotation, and the scout wasn’t exactly a fan of the transition:

“I hope they do start him, but they’re crazy if they do,” said the scout, who works for another National League club. “It’s Joba Chamberlain all over again.

“His velocity dropped off in the second inning. He couldn’t get his off-speed stuff over the plate consistently. No question in my mind, he’s the closer.”

Chapman averaged 97.7 MPH on his fastball last season, the second-fastest among all relievers, trailing only Kelvin Herrera of the Kansas City Royals (98.5). He finished the year with a 1.51 ERA and 38 saves in 71.2 innings of work.

The scout is referencing the Yankees pitcher who bounced between the bullpen and the rotation since making his Major League debut in 2007. The Yankees went to great lengths to protect his arm, which led to the moniker “Joba Rules” for their refusal to use him on consecutive days.

Though a closer more often than not pitches in some of the most important situations during a game, it is hard to overcome the value of pitching 175-200 innings. John Smoltz, a common point of comparison for starters-turned-relievers or relievers-turned-starters, posted 1.1, 3.2, and 2.2 Wins Above Replacement as a reliever between 2002-04 according to Baseball Reference. Despite the aggregate 2.47 ERA and 144 saves, his best season as a reliever (2003) ranks as his 12th-best season by WAR.

Chapman would have to become more or less average as a starter for the Reds to lose value moving him to the rotation. The average National League starter posted a 4.04 ERA last season.

The Astros’ bullpen did yeoman’s work in place of the injured Dallas Keuchel on Monday against the Tigers. Keuchel is temporarily sidelined with a pinched nerve in his neck.

Brad Peacock made the spot start, limiting the Tigers to one hit and two walks with eight strikeouts over 4 1/3 innings. Chris Devenski took over with one out in the fifth, finishing out that inning as well as the sixth and seventh, facing the minimum. Will Harris pitched a perfect eighth and Ken Giles closed out the 1-0 victory in the ninth. Devenski, Harris, and Giles each had two strikeouts.

The Astros scored their only run in the bottom of the first inning as George Springer drew a leadoff walk, then scored on Jose Altuve‘s one-out double. Tigers starter Brad Fulmer pitched well enough to win on most days, giving up the lone run in seven frames.

After Monday’s win, the Astros became the first team to reach 30 wins, sitting on a 30-15 record. With a +55 run differential, even their expected record matches up with their actual record.

Braves second baseman Brandon Phillips became the 337th player in baseball history to hit 200 career home runs, driving a solo home run to left-center field during Monday night’s home game against the Pirates. Phillips is the 14th second baseman (who played a min. of 75 percent of his career games at the position) to rack up at least 200 career home runs.

Phillips, 35, entered Monday’s action batting .290/.345/.405 with two home runs and 12 RBI in 142 plate appearances. If he’s anything, he’s consistent, as he finished with an adjusted OPS between 90-99 (100 is average) every year between 2012-16 and it was sitting at 97 coming into Monday.
