Rotation, Reimold and a reheated leftover

A reader asked earlier today about the Orioles' rotation for the Cardinals series that begins tomorrow night at Camden Yards. Zach Britton, Chris Jakubauskas and Brian Matusz are the scheduled starters. Jakubauskas will work on normal rest and take Jake Arrieta's turn. Arrieta, as you'll recall, is slated to throw another bullpen session on Wednesday and make Saturday night's start in Atlanta. The Cardinals are batting .276 against right-handers and .247 against left-handers. They're hitting .258 at home and .278 on the road. The Cardinals are starting right-handers Kyle Lohse, Chris Carpenter and Jake Westbrook. That could mean three more Orioles lineups that won't include Nolan Reimold. Reimold hasn't started since June 19 in Washington, when he went 1-for-4 with a run scored. He's appeared in one other game, on Wednesday afternoon in Pittsburgh, but he didn't get an at-bat. Reimold's previous start before the Nationals game was June 15 in Toronto. The Orioles aren't facing many left-handers, and Luke Scott is going to get the bulk of the starts against right-handers, with Felix Pie the other option. Vladimir Guerrero clogs up the designated hitter spot. There's no rotating system in place as long as he's on the roster. Reimold has to be content with periodic starts and pinch-hitting opportunities. Here's a leftover from yesterday: Reds left-hander Aroldis Chapman hadn't allowed a home run to a left-handed batter this season until Scott took him deep in the seventh inning. Chapman was hitting 100 and 101 mph with his fastball in his two appearances over the weekend, but Scott launched a 94 mph fastball. At least, we assume it was a fastball. With Chapman, it could have been his changeup. Upon further review, it was the first home run Chapman allowed in 33 major league games. Even better.
