A's recall RHP J.B. Wendelken from Triple-A Nashville

RHP Daniel Mengden optioned to Nashville

The Oakland A's recalled right-handed pitcher J.B. Wendelken from Triple-A Nashville and optioned right-handed pitcher Daniel Mengden to Nashville, the club announced today.

This will be Wendelken's third stint with the A's this year. He was originally called up on May 8 and made his Major League debut that afternoon at Baltimore. He appeared in two games before being optioned back to Nashville on May 9. He was recalled again on June 3 but did not pitch before being optioned the following day.

The right-hander was acquired by the A's with left-handed pitcher Zack Erwin from the Chicago White Sox for infielder Brett Lawrie on Dec. 9, 2015. This season with Nashville, Wendelken is 1-4 with five saves and a 4.66 ERA in 33 games, all in relief. He posted a 0.90 ERA in 10 games in April, but had a 7.79 ERA in 16 games in May and June. So far in July, he is 0-1 with a 2.89 ERA.

After stops in both Double-A and Triple-A to start the season, Mengden was selected by the A's on June 11 and made his Major League debut that day at Cincinnati. Over his first four starts with the A's, he went 1-3 with a 2.81 ERA, but is 0-2 with a 9.00 ERA over his last five starts and 23 innings pitched. After tossing at least 5.2 innings in each of his first four starts, he's lasted 5.1 innings or fewer in each of his last five.

Mengden was originally acquired with catcher Jacob Nottingham from Houston for left-handed pitcher Scott Kazmir on July 23, 2015.
