Minor MLB Transactions: 7/24/15

Here are the day’s minor moves:

• The Cubs have optioned lefty Clayton Richard, Carrie Muskat of MLB.com tweets. It appears that the previously reported DFA only removed him from the 25-man roster, to permit the club to seek optional assignment waivers. Richard could have declined the assignment himself, but apparently chose not to.
• The Blue Jays have released infielder Ramon Santiago, as Ben Nicholson-Smith of Sportsnet.ca reports on Twitter. Santiago, 35, slashed just .202/.283/.218 in his 139 plate appearances this year at Triple-A Buffalo. He has seen big league action in 13 straight seasons, but now seems likely to see that streak come to an end.
• Toronto has also added righty Phillippe Aumont, Sportsnet’s Shi Davidi tweets. The former Phillies hurler has never gained traction at the big league level, and hit the open market after declining an outright assignment. He did post a 2.35 ERA over 65 innings at the Triple-A level this year, his best showing in some time.
• Lefty Ryan Buchter has agreed to a minor league deal with the Cubs, Darren Wolfson of 1500 ESPN reports on Twitter. The 28-year-old was released by the Dodgers recently after exercising his opt-out. Buchter threw 32 2/3 innings of 1.65 ERA ball at Triple-A, with 10.7 K/9 against 4.4 BB/9.
