The Cubs have traded left-hander Paul Maholm, outfielder Reed Johnson and cash considerations to the Braves in a four-player trade that provides Atlanta with reinforcements for the season's final two months and bolsters Chicago's minor league system. The Cubs obtain right-handers Jaye Chapman and Arodys Vizcaino in the trade, which the teams have announced.

Maholm has a 3.74 ERA with 6.1 K/9, 2.5 BB/9 and a 49.9% ground ball rate in 120 1/3 innings for the Cubs this year. The 30-year-old has never thrown particularly hard; his average fastball checks in at 87.6 mph this year, according to FanGraphs. He earns a $4.75MM salary in 2012 and his contract includes a $6.5MM club option for 2013. The Royals and Pirates appeared to have interest in Maholm earlier this month.

Johnson, 35, has a .307/.361/.452 batting line in 180 plate appearances this year. The right-handed hitter has played all three outfield positions for the Cubs and owns a career .313/.370/.469 line against left-handed pitching. He's signed to a one-year, $1.15MM contract and will hit free agency after the season. Four teams made offers for Johnson today, including the Pirates and Tigers, according to Bruce Levine of ESPNChicago.com.

Vizcaino, who entered the 2012 season ranked by Baseball America as the 40th-best prospect in MLB, had Tommy John surgery this spring. The 21-year-old posted a 3.06 ERA with 9.3 K/9 and 2.6 BB/9 in 97 innings for three Braves affiliates as he made his way through Atlanta's minor league system in 2011. The right-hander reached the Major Leagues last year, posting a 4.67 ERA with 8.8 K/9 and 4.7 BB/9 in 17 relief appearances.

Chapman, a 25-year-old right-hander, has a 3.52 ERA with 10.1 K/9 and 4.9 BB/9 in 53 2/3 innings of relief for Atlanta's Triple-A team so far in 2012. The Braves selected him in the 16th round of the 2005 draft.

Maholm joins a Braves rotation that includes Tim Hudson, Tommy Hanson, Mike Minor, Ben Sheets and, as of tomorrow, Kris Medlen. The Braves nearly traded for Ryan Dempster this month, but the sides don't appear to have obtained the right-hander's permission.

Geovany Soto has been traded to the Rangers in a separate move.
