A battle of American League division leaders is on tap for Tuesday night as the Tampa Bay Rays play host to the Los Angeles Angels. Here's your Daily Sports Roundup . . .

Event of the day . . .

The Angels are running away with the AL West title this season - unless the Rangers can find some consistency Los Angeles will likely be the only team in that division that ends up above the .500 mark. The Rays find themselves a little more challenged from the likes of the Red Sox (and potentially the Yankees) in the AL East race, but they've already managed to set the franchise mark for victories in a single season.

James Shields (10-7, 3.75 ERA) will get the ball for Tampa Bay on Tuesday night, and the Rays have picked up the win in each of his last three outings. In fact, Tampa Bay is 8-2 over Shields' last 10 trips to the mound. The righthander has faced Los Angeles twice already this season, getting knocked around for earned six runs in a loss on June 10, and tossing nine shutout, one-hit innings in a win back on May 9.

Ervin Santana (13-5, 3.49 ERA) will start for the Angels. The righthander is coming off a no-decision versus the Mariners in which he gave up three earned runs on seven hits over 6 1-3 innings of work. Santana had won each of his previous two starts, and Los Angeles is 6-4 over his past 10 outings. Santana faced the Rays back on May 11, giving up five earned runs on nine hits over 5 2-3 innings to get tagged with the loss.

Non-event of the day . . .

The Royals and the Indians will continue their fight for fourth place in the AL Central when they hook up in Cleveland on Tuesday night. Kansas City is scheduled to send Luke Hochevar (6-11, 5.44 ERA) to the mound in that contest, while Cleveland will counter with Anthony Reyes (1-1, 2.19 ERA). Reyes was picked up from the Cardinals to provide a stop-gap for the Tribe's rotation through the end of their wasted season.

Also on the schedule . . .

Daisuke Matsuzaka (14-2, 2.74 ERA) will look to pitch the Red Sox past the Orioles on the road on Tuesday. Other American League matchups on the schedule: the Yankees at Toronto, Detroit at Texas, Oakland at Minnesota, and Seattle at the White Sox.

There's also a full slate of National League games on Tuesday, highlighted by the Brian Moehler (8-4, 3.97 ERA) / Ben Sheets (11-6, 3.00 ERA) duel in the Astros/Brewers matchup.
