ST. LOUIS -- Fortunately for the Giants, they don't spend their free time reviewing the team's day-by-day performances from previous seasons.

Otherwise, they'd be wary of June's arrival on the calendar.

The "June Swoon" was a malady that regularly struck the Giants when they were perennial contenders from their arrival in San Francisco through the early 1970s. They'd be near or at the top of the league or division standings until a subpar or downright terrible June record would drain their momentum.

Since then, the team has mostly avoided such slumps, though the malady has returned occasionally. During Bruce Bochy's first season as San Francisco's manager in 2007, the Giants owned a 25-27 record at the end of May -- but were only 5 1/2 games out of first place. Then, a 9-18 June left them 12 games back.

The Swoon initially manifested itself during the franchise's inaugural year out West in 1958. The Giants were tied for first in the National League with a 27-17 mark. A 10-17 June dropped them to third place, three games out.

Two years later, it cost manager Bill Rigney his job. He was fired in the middle of an 11-16 June that followed a 26-16 start and moved the Giants from 1 1/2 games out of first to six games back.

Other notable dips occurred in 1968 and 1973, when sub-.500 Junes sent the Giants tumbling from a half-game lead to 6 1/2 back, and 1971, when they lost more games in June (15) than in the season's first two months (14).

Bochy discusses weekend lineup plans

COL@SF: Pagan delivers walk-off inside-the-park homer

ST. LOUIS -- Manager Bruce Bochy reiterated that center fielder Angel Pagan "possibly" could return to the Giants' lineup in the second game of Saturday's split doubleheader against the Cardinals.

But Bochy also acknowledged that the slick field conditions might keep Pagan, who has been sidelined with a strained left hamstring since last Saturday, on the bench.

The glut of three games over two days prompted Bochy to distribute playing time more than usual. He said that Nick Noonan would play both ends of Saturday's doubleheader, starting the opener at third base and the nightcap at second. "He's the young buck," Bochy said of Noonan, 24.

Bochy reasoned that by stationing Noonan at second base in Game 2, Marco Scutaro could rest and Joaquin Arias could start at third. Bochy figured that Arias' presence could be advantageous, since he's more experienced at third than Noonan and, with left-hander Madison Bumgarner on the mound, is likely to receive more fielding chances than usual.

Like Noonan, first baseman Brandon Belt likely will play both of Saturday's games before resting on Sunday, Bochy said. Brett Pill will fill in at first base for the series finale.

Bochy said Guillermo Quiroz would probably catch Game 2 in place of Buster Posey, whom he said would return behind the plate on Sunday.
