Since their Cleveland days, they have started against each other once -- last year on May 16. Westbrook and the Cardinals got the better of Lee that day, beating the Phillies, 3-1.
On Saturday, the former teammates will face each other again in the second game of the Cardinals' three-game series in Philadelphia.
In his last start, Sunday against the D-backs, Lee allowed three home runs in eight innings. He has given up seven home runs in 22 innings in his last three starts. He has already matched last season's total of 18, despite throwing nearly 100 fewer innings.
"The home runs, I've got to do a better job of keeping the ball down, keeping it in the ballpark," Lee said. "When it's hot here, the ball really travels and that's when I've got to be more conscious of keeping the ball down, induce more ground balls."
Westbrook knows a little about getting ground balls. He leads the National League in ground-ball-to-fly-ball ratio (2.63) and ground-ball percentage (72.4). The sinkerballer is on a four-game winning streak and has pitched at least six innings in 11 straight starts.
Westbrook has had trouble with his control recently, but he said Monday's start against the Giants was better.
"The key for me is getting ahead and controlling counts, which I did a good job of [Monday]," Westbrook said. "It's good to get back on track in that sense."
Phillies: Manuel plans on moving Brown around outfield
Before Friday, Domonic Brown had exclusively played left field since being called up from Triple-A Lehigh Valley for the first time this season. In the series opener against the Cardinals, however, Brown started in right field.
Manager Charlie Manuel said he wants to use the last two months of the season to "look at what guys can do." Manuel said Brown might get a chance to play all three outfield positions.
Brown is hitting .281 and is slugging .375 in 10 games since returning to the Major Leagues.
Cardinals: Jay solidifying himself at the top of the order
Center fielder Jon Jay has started three games in a row at leadoff for the Cardinals, and so far, the results have been good. Jay went 1-for-4 in the Cardinals' 3-1 loss to the Phillies on Friday and is 5-for-11 with two stolen bases in the last three games. Jay is riding a five-game hitting streak and is batting .307 with a .380 on-base percentage this season.
Manager Mike Matheny said he's looking for a patient hitter at the top of his lineup, which Jay has been this season.
"You want [your leadoff hitter] to work the count a little better and the bottom line is getting on base," Matheny said. "It's a guy that can't be afraid to be patient."
Cardinals shortstop Rafael Furcal has been battling a bad back, but he will likely be happy to see Lee on the mound. He is 5-for-14 with two home runs and a triple in his career against the left-hander.
