Among those who figure to be recalled are Trevor Bell, Garrett Richards, Tyler Chatwood and Michael Kohn.
Chatwood and Richards, like Bell, are starters who give the Angels flexibility with his ability to pitch in any role. Kohn has racked up impressive numbers of late at Triple-A Salt Lake after a few rough outings led to his demotion on July 20.
"He's definitely throwing the ball better," Angels manager Mike Scioscia said of Kohn, the right-hander with the power arm. "He has much better command."
Kohn has 62 strikeouts against 19 walks in 45 1/3 innings at Salt Lake. Kevin Jepsen, a valuable setup man for the Angels in 2009 and 2010, apparently is down for the season with a knee injury expected to require surgery. Jason Bulger, another productive former Angels reliever, also has been pitching impressively at Salt Lake but is not on the 40-man roster. The same holds for versatile outfielder Reggie Willits.
