Robertson struck out two in a perfect ninth inning to earn his fifth save of the season in Thursday's 3-1 win against the Twins.

EDGE Analysis

The 31-year-old is now 5-for-5 in save opportunities and on a record-breaking pace to start 2016. Robertson has yet to allow a hit and has only walked one while striking out six in five innings of work.

Robertson earned his second save of the season with a perfect ninth inning against the A's on Tuesday.

EDGE Analysis

Following Jimmy Rollins' go-ahead home run in the top of the ninth, Robertson made quick work of the A's, retiring the side on 13 pitches. Robertson issued a leadoff walk in his first save chance Monday, but then went strikeout, flyout, groundout to end it. He only pitched on three consecutive days twice last season.

Robertson picked up his first save in Monday's Opening Day win over the Athletics. He struck out one and gave up a walk, but no hits.

EDGE Analysis

Robertson was able to work around the leadoff walk without incident. His peripherals were great as usual last season (12.2 K/9, 1.85 BB/9), but he finished with a mediocre 3.41 ERA. Robertson's stuff is just about as good as it gets among closers, but he last posted an ERA below 3.00 in 2013. If he can keep the ball in ballpark this year, get back to that level again.

Robertson tossed a scoreless inning in his spring debut Tuesday afternoon.

EDGE Analysis

He hit the first batter he faced, but Robertson induced a double play from Adrian Gonzalez before getting Scott Van Slyke to ground out to end the inning. Robertson enters Year 2 of his four-year deal with the White Sox having a firm hold on the closer's role, with the potential to improve upon the 3.41 ERA he posted over 60 appearances last season.

Robertson tossed a clean ninth inning to record his 32nd save in the White Sox 5-2 win over the Yankees on Friday night.

EDGE Analysis

Robertson has 32 saves in 39 chances - certainly not an automatic ending to games, and he has suffered a rough September. He went through a stretch of three games where he allowed nine runs (seven earned), and that has been a good depiction of his season - stretches of dominance, and stretches of extreme vulnerability.

Robertson managed to secure his 30th save in spite of surrendering three hits and two earned runs in one inning in Saturday's 4-3 win over the Indians. He also struck out a batter.

EDGE Analysis

It marked the third consecutive outing in which Robertson has made it interesting in the late innings, with the White Sox closer giving up a one-out, two-run homer in the ninth to Kelly Johnson to pull the Indians within a run. The veteran reliever then surrendered a single to Abraham Almonte and eventually secured the final out of the ballgame, and the save, by picking him off first base. Despite Saturday's narrow escape, Robertson's 21.00 ERA and two homers surrendered over his last three innings has to be somewhat concerning to both his team and fantasy owners.

Robertson (6-4) took the loss and was charged with his seventh blown save of the season in a 4-2 defeat to the As on Thursday. He surrendered three hits, three earned runs and walk in one inning while also striking out a batter.

EDGE Analysis

Robertson invited trouble by yielding a one-out double to Brett Lawrie and a single by Danny Valencia before Billy Butler plated both with a blast to right field. After a streak of eight consecutive appearances without allowing an earned run, Robertson has now given up seven runs (five earned) over his last two innings. The blown save also broke a streak of six consecutive successful conversions of save opportunities for the veteran reliever.

Robertson was claimed off revocable waivers by the Yankees on Monday, but a deal is highly unlikely, CBS Sports reports.

EDGE Analysis

The White Sox likely placed Robertson on waivers hoping he would go through unclaimed, and now the likely scenario involves the club taking him off waivers and keeping him. Assuming that's the case, he should continue in the White Sox's closer role the rest of the way.

Robertson pitched two perfect innings against the Marinrs on Sunday to earn his sixth win of the season.

EDGE Analysis

It was his first time throwing two innings since early-June, and the 29 pitches were the fourth-most he has thrown in a game this season. With an off-day Monday, the extra effort should not impact his availability for the team's upcoming series against the Twins.

Robertson worked a perfect ninth inning Saturday, striking out one, to notch his 18th save of the season. Not much has gone right for the White Sox so far, but Robertson at least has been as effective as advertised as their closer and he now sports a 2.60 ERA, 0.95 WHIP and 49:7 K:BB ratio in 34.2 innings on the season.
