Ross went 2-for-4 with a solo homer and two runs scored overall in Friday's 12-1 victory over the Mariners.
The veteran backstop kick-started a six-run sixth for the Cubs, blasting a 382-foot solo shot to left center off Nate Karns. Ross has played very sparingly in July after suffering a concussion early in the month, logging only 14 at-bats, three hits and two RBI.
Heyward went 1-for-4 with a sacrifice fly and two-run homer in Friday's 12-1 victory over the Mariners.
It was only his fifth long ball of the year and first since way back on June 11 against the Braves. Heyward's power drought over his first Cubs campaign has been relatively surprising, given that he's put together six straight double-digit homer seasons to start his career. The 26-year-old has endured a rough month of July as well, with only six extra-base hits and five RBI over 84 at-bats.
Rizzo went 1-for-5 with a bases-clearing double and a run in Friday's 12-1 victory over the Mariners.
The slugging first baseman helped to break the game wide open with his sixth-inning, bases-loaded two-bagger, plating Jon Lester, Chris Coghlan and Kris Bryant. Rizzo came up with the bases jammed again in the seventh, and his double play groundout allowed Matt Szczur to score on a fielder's choice. The 26-year-old has enjoyed a solid July, raising his average 18 points since the first game of the month.
Bryant went 3-for-3 with an RBI single, double, two walks and a run in Friday's 12-1 victory over the Mariners.
The 25-year-old is putting the finishing touches on a rock-solid July, hitting safely for the 11th time in the last 12 games. Bryant also has four multi-hit efforts over that span and six overall during the month. The All-Star is slashing .301/.408/.506 over 83 July at-bats.
Lester (11-4) pitched six scoreless frames in Friday's 12-1 victory over the Mariners, giving up only four hits and two walks while recording seven strikeouts.
The ace southpaw has gotten the second half off to a relatively solid start after a pair of worrisome efforts immediately before the All-Star break. Lester induced 13 swinging strikes in Friday's victory, pitching well for the second time in three post-All-Star-break trips to the mound. The 32-year-old also recorded seven strikeouts for the second straight appearance and will look to continue building momentum when he takes on Jose Fernandez and the Marlins at Wrigley next Wednesday.
