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

39 Comments

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.

Mariners outfielder Mitch Haniger left Tuesday night’s game against the Tigers with a strained oblique, Ryan Divish of the Seattle Times reports. Haniger suffered the injury running after hitting a single in the third inning. He was 2-for-2 when he exited the game.

Haniger will almost certainly be placed on the 10-day disabled list as a result of the injury. It’s a big loss for the Mariners, as he entered the night batting .321/.430/.590 with four home runs and 16 RBI in 93 plate appearances.

Danny Valencia, who pinch-ran for Haniger and stayed in the game to play right field, is likely to take Haniger’s spot in the lineup and in the outfield during his absence.

Astros second baseman Jose Altuve and outfielder Teoscar Hernandez collided attempting to catch a shallow fly ball hit by Indians catcher Yan Gomes in the bottom of the eighth inning during Tuesday night’s game.

Hernandez, who was called up earlier on Tuesday, had just come into the game as a defensive replacement for Carlos Beltran. George Springer entered the game in right field in Hernandez’s place after Hernandez was carted off the field. Altuve was replaced at second base by Marwin Gonzalez.

The Astros should have updates on the conditions of both players after the game. Losing Altuve would be a big deal for the first-place Astros, as he entered the game batting .324/.393/.459 with seven stolen bases.
