Robertson struck out two in a perfect ninth inning to save the White Sox's 5-4 victory over the Red Sox on Monday.
Perceptions can change quickly in baseball. Entering the Memorial Day weekend, Robertson hadn't had a save opportunity in nearly a month and converted just five saves -- last among front-line closers that have pitched all season -- but he saved a third straight game for the White Sox and bumped his season total up to eight. A closer that may have been regarded as having low value changed that perception over a holiday weekend. If pitching three straight days (30 pitches) means Robertson is unavailable Tuesday, it's unclear which reliever manager Rick Renteria will call upon if a closer is needed. Tommy Kahnle might be the first choice but he's pitched three of the last four days. After Kahnle, Anthony Swarzak is next in line.
