Daniel Mengden has right foot surgery

Oakland A's right-handed pitcher Daniel Mengden had successful surgery on his right foot today at Houston Methodist Hospital. Mengden fractured his medial tibial sesamoid bone while throwing a bullpen at home Jan. 31. The surgery, which involved a sesamoidectomy, was performed by Dr. Kevin Varner. Mengden is expected to be in a walking boot for six weeks. There is no further time table for his return.

Mengden made his Major League debut with Oakland last year in his third professional season after beginning the year with no experience above Single-A. He went 2-9 with a 6.50 ERA in 14 starts over two stints with the A's and combined for a 10-2 record, a 1.46 ERA and .197 opponents batting average in 17 starts with Double-A Midland and Triple-A Nashville. The 23-year-old tied for fourth among American League rookies in games started and ranked 10th in innings pitched (72.0) and strikeouts (71).
