Extra bases

• The Cubs held a moment of silence on Monday for former Cubs pitcher Frank Castillo, who died Sunday in a swimming accident at Bartlett Lake in Arizona. He was 44.

The Cubs drafted Castillo in 1987, and he pitched for the team from 1991-97, compiling a 47-62 record and 4.29 ERA in 166 games (161 starts). He spent last year as a pitching coach for the Cubs' Rookie League team.

• Javier Baez hit two home runs, but it wasn't enough as Double-A Tennessee lost 8-5 to Birmingham on Sunday. He hit a two-run homer in the first and a two-run shot in the ninth. After batting .274 with 17 home runs at Class A Daytona this year, Baez now is batting .232 with 10 home runs with the Double-A Smokies.

• C.J. Edwards had quite a debut Sunday for Class A Daytona. He struck out the first seven batters he faced, and finished with eight strikeouts over five scoreless innings, giving up one hit and walking one in a 2-1 win over Palm Beach. The Cubs acquired Edwards in the Garza deal with the Rangers.

• Brett Jackson, the Cubs' No. 1 pick in the 2009 Draft, has joined the Double-A Tennessee roster. Jackson, 24, began the season at Triple-A Iowa, but has been slowed by a turf toe injury and problems with his right calf. In 61 games with Iowa, he batted .223 (48-for-215) with seven doubles, three triples, six home runs and 23 RBIs. He spent part of the 2010 and '11 seasons with the Smokies.

• Scott Baker, rehabbing from Tommy John surgery on his right elbow, gave up two runs, one earned, on three hits and two walks over 3 1/3 innings for Class A Daytona in a rehab start on Monday. Baker struck out two and served up a solo home run in the fourth.
