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.

Jonny Venters is still pitching

Lefty reliever Jonny Venters was among a handful of players the Rays signed to minor league contracts, Marc Topkin of the Tampa Bay Times reports.

Venters, 32, hasn’t pitched in the majors since 2012 and has logged just 27 2/3 innings in the minors in the meantime due to a continuous battle with his elbow. According to David O’Brien of the Atlanta Journal-Constitution, Venters has undergone four — four! — Tommy John surgeries.

When he was healthy, Venters was a fearsome late-game option for the Braves. He posted a 1.95 ERA with 93 strikeouts in 83 innings in 2010, and a 1.84 ERA with 96 strikeouts in 88 innings in 2011. His first-half performance in 2011 earned him a spot on the National League All-Star roster.

Venters has spent the last two years in the Rays’ system and he’ll try to make it a third.
