The second half began in a familiar way for the Oakland Athletics who fell to the Minnesota Twins 5-4 Friday night. However, there is a hint that the second half of the season could be just a bit more intriguing. The A’s called up two of their top three prospects in Tyler Soderstrom and Zack Gelof and both made their major league debuts Friday night. The A’s also moved a trio of prospects in Lawrence Butler, Brett Harris and Darrell Hernaiz to Triple A. Could we see any of that group in Oakland before the end of the season.
