(Sports Network) - Journeyman southpaw John Parrish starts against his former team for the first time tonight when the Toronto Blue Jays host the Baltimore Orioles in the finale of a three-game series at Rogers Centre.

A 26th-round draft pick in 1996, Parrish reached the majors with the Orioles in 2000 and stayed with them through part of the 2007 season, making 153 appearances - 10 starts - while going 12-12 withh a save in 219 innings of work.

He finished 2007 by making eight appearances with Seattle, then debuted with the Blue Jays on June 28, defeating Atlanta, 9-5, with six innings of four- hit, one-run ball with four strikeouts.

A 30-year-old native of Lancaster, Pennsylvania, Parrish has a career earned run average of 4.55 and has allowed an opposition batting average of .260.

Baltimore righty Jeremy Guthrie looks for a third straight win overall and a second straight defeat of the Blue Jays.

The former first-round draft choice (22nd overall, 2002) beat Toronto, 9-5, on June 7, allowing six hits and a run with six strikeouts in seven innings.

He's lost just once in five starts since, including victories against the Chicago Cuns and Texas Rangers on June 24 and July 4, respectively.

Guthrie is 3-4 in 10 road starts with a 3.71 ERA. On Wednesday, Alex Rios and David Eckstein each drove in two runs, as the Blue Jays used a seven-run fourth inning to defeat the Orioles, 9-8.

Rios and Eckstein both had two hits and a run scored for Toronto, which has won three of its last four. Vernon Wells was 2-for-4 and scored twice, but left following the sixth inning with leg cramps.

Nick Markakis homered and scored three runs in a three-hit performance while Adam Jones added a three-run homer for Baltimore, which dropped its fourth straight.

A.J. Burnett (9-8) failed to impress for the second consecutive outing, but got the win thanks to the superior offense.

Burnett, who improved to 6-1 lifetime against the Orioles, allowed seven runs on seven hits and three walks in 5 1/3 frames.

The right-hander is auditioning for a host of teams, as he now heads a short list of pre-trade deadline pitching commodities following Cleveland's dealing of ace southpaw CC Sabathia to Milwaukee and Oakland sending Rich Harden to the Chicago Cubs.

He did fan seven, but was already coming off a disappointing six-run, 12-hit loss to the Angels.

Garrett Olson (6-4) took the loss, as he was shelled for seven runs on seven hits in only 3 2/3 innings.

Toronto has won four of its seven meetings with the Orioles this season.
