Vogelsong gave up one run -- a Pablo Sandoval solo homer -- in four innings Monday, allowing four hits and a walk while striking out two.

EDGE Analysis

He took a shot off his pitching hand on a Hanley Ramirez comebacker but remainded in the game. Vogelsong is expected to start the season as Pittsburgh's fifth starter. The 38-year-old compiled a 4.67 ERA, 1.47 WHIP and 108:58 K:BB ratio in 135 IP for San Francisco in 2015. The Pirates are hopeful he serves as a first-half bridge to some of their prospects such as Tyler Glasnow and Jameson Taillon.

Vogelsong signed a one-year contract with the Pirates on Friday, Stephen J. Nesbitt of the Pittsburgh Post-Gazette reports.

EDGE Analysis

The long-time Giant will head east to join the Pirates on a one-year deal and compete for a spot in the back of the Pittsburgh rotation. Vogelsong struggled as a starter in 2015, compiling a 4.50 ERA with a 1.80 K:BB ratio over 116 innings of work. That said, Vogelsong is just one year removed from a strong season in which he had a 3.85 FIP and 2.60 K:BB.

Vogelsong entered Monday's game as a reliever, John Shea of the San Francisco Chronicle reports.

EDGE Analysis

Vogelsong is listed as the starter for Tuesday's game, but he'll apparently be scratched, and the team is yet to announce a replacement. The right-hander was shelled for eight runs in his last start, though the motive behind the move to use him as a reliever is unknown.

Vogelsong (9-11) was bombed for eight runs (seven earned) on 11 hits over three innings in Thursday's 11-3 loss to the Rockies.

EDGE Analysis

Vogelsong has failed to escape the fifth inning in three consecutive turns, taking the loss on each occasion. He's at least been a useful streaming option at AT&T Park, where he's gone 3-3 with a 3.29 ERA and .224 batting average against in 54.2 innings, but with his next start set to come in another bandbox in Arizona, dropping him may be a prudent move at this stage of the season.

Vogelsong turned in another short, ineffective performance Saturday, allowing four runs on seven hits and three walks over 4.2 innings while striking out three.

EDGE Analysis

He's gotten out of the fifth inning just once in his last five starts, and the only thing keeping Vogelsong in the rotation right now is Matt Cain's sore elbow. Don't expect any kind of turnaround in his next start, when the Giants travel to Coors Field on Thursday.

Vogelsong (6-6) allowed four runs on five hits and three walks in 5.2 innings against the Phillies on Saturday, striking out three in a no-decision. San Francisco's offense put up seven runs against the Phillies bullpen to save Vogelsong from a potential loss after he exited trailing 4-1. Vogelsong has done himself no favors lately, allowing nine runs in 15.2 innings over his last three starts, and the 37-year-old is walking almost four batters per nine innings in what has been a disappointing season to date. The All-Star break couldn't come at a better time for Vogelsong, as it will him a chance to put his recent struggles behind him heading into the second half. Vogelsong is 0-1 with a 6.57 ERA in two starts against the Phillies this year, so there may not be any matchup in which owners can trust him at the moment.

Vogelsong allowed one run on three hits and three walks in just four innings Sunday against the Nationals. He did not factor into the decision. The veteran didn't have his best stuff Sunday, as he threw just 44 of his 71 pitches for strikes in the abbreviated outing. Vogelsong has been a little erratic lately, sandwiching a pair of shutout victories in between four poor outings, and will look to bounce back Saturday with a favorable matchup against the Phillies.

Vogelsong fell to 6-6 after allowing four runs on seven hits and three walks over six innings in a loss Tuesday against Miami. He struck out four. Vogelsong gave up at least four runs for the sixth time in 16 starts. He also has three shutout starts of at least six innings. Vogelsong's numbers are mediocre (4.19 ERA, 63:36 K:BB), but he may have additional value in formats that reward the occasional great start over steady consistency.

Vogelsong (6-5) threw six scoreless innings, striking out four and giving up five hits and two walks in Wednesday's win over the Padres. Vogelsong picked up his second straight win, back-to-back shutouts against the Mariners and the Padres. After an excellent May in which he went 4-0 with a 1.14 ERA, Vogelsong struggled to start off the month of June but is now on a scoreless streak of 12.2 innings. He'll look to add to that streak in his next scheduled start Tuesday at Miami.

Vogelsong (5-5) struck out six and gave up three singles and two walks in 6.2 scoreless innings in Thursday's win over the Mariners. Vogelsong rebounded from a rough outing with his best start in almost a month, though it came against the offensively challenged Mariners, who were held to two runs or less for the 26th time in 67 games. After going 4-0 in five starts in May with a 1.14 ERA, Vogelsong was 0-3 with a 6.61 ERA in his first three starts in June. He'll look to build on his solid performance Thursday when he faces off against the Padres on Wednesday in his next scheduled start.
